Theories and Experiments

I'm about a third of the way into Nisargadatta Maharaj's I Am That, and he is finally beginning to get interesting in and of himself.

"Theories are neither right nor wrong.  They are attempts at explaining the inexplicable.  It is not the theory that matters, but the way it is being tested.  It is the testing of the theory that makes it fruitful.  Experiment with any theory you like--if you are truly earnest and honest, the attainment of reality will be yours.  As a living being you are caught in an untenable and painful situation and you are seeking a way out.  You are being offered several plans of your prison, none quite true.  But they are of some value, only if you are in dead earnest."
